Mobile Power Grounding Units

The A-2-Sea Mobile Power Grounding Unit (MPGU) is an important product for power safety and provides the ability to work on potentially live branched cable systems during installation and repair.

The MPGU is a system for verifying earth connections and constant monitoring for current on the cable – current detected over 100mA activates alarms.

Consisting of a Robust Design Concept which is lightweight and portable (incorporating battery charger with backup battery), the MPGU is a very flexible unit and can be used in a variety of environments such as beach manholes and on board barges or vessels of opportunity. In repair scenarios, the MPGU can be used with various Subsea and Beach Joint Technologies.
